To all whom it may concern.-

Be it known that I, CHARLES Forum, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invehted a new and useful Imand accompanying drawings.

My inventionconsists of- 'a pistol or other fire-arm which isrprovldedwith means for retaining the revolving chamber or cylinder in operativeposition, the same being readily so-as to permit the removal of Figuralrepresents a side elevation partly broken away of a; pistol embodying myinvention, the niuzzlebeing depressed. Fig.2 represents'a. partial sideelevation and partial longitudinal section of a portion of the pistol,the muzzle being elevated. Fig. 3 represents aisection of a portion.

Fig. 4 represents anend view of the cylinder and" connected por tions.-Fig. 5 represents anend view of the trigger. Similar letters'ofreference indicate corresponding parts in the several. figures.

Referring" to the drawings: A designates my invention applied theretoare of usual the barrel, there-isa chamber 0, in which is located thespring-actuated catch D of angutruding through the opening F in saidstrap. The nose G which is on theother limb of said catch is adapted tofreely engage with the chamber is permitted to rotate, it is preventedlocking action of said nose G. When" the limb E is properly depressed,the nose. G moves. away fiom the end of the chamber, beyond theperiphery thereof, and thus the chamber may be withdrawn, as: shown. in'dotted lines for any purpose required. When the chamber isrestoredto-position, the nose G again engages with the chamber'and controls thelongitudinal motion of the same.

chamber A, is a spring catch K, whose head K is adapted to enter aportion of either recess L in the chamber A, the portion otsai'd to beraised by the same, the tendency of said catch being to lower,. whi'chit does when: the trigger is pulled. In the trigger'is a vertical recessN, which is occupied by the shank of a will'behereinafter explained.

In the chamber are recesses Q, which exrecesses 'L, so that when thecatch P rises and properly guided into the recess L.

said lip is formed with a recess R tore'ceive said head, .as mostclearly shown in'Figs'. 3 and 5. It will be seen that when the triggeris by the lip M of thetrigger. Consequently the head K? of said catchoccupies-a-portion 'ot the adjacent recess'L, and thereby locks thechamber and prevents ,rotation'ofthe same. As the rearportion'ot-thetrigger-is ever the pistol 'is to be discharged, and the from the.recess L,:.'whereby the chamber is as the rear end. ofthe-triggerrises,,the catch P is raised and it contacts yieldingly withthe periphery of the chamber, and then enters the recess Q, whichhasjadvanced toward it, after which it drops-into .the portion o'f therecess Q, whereby the Connected with the trams J, below the catch,-ne arthe head thereof, resting on-the' lipM, at the forward part of thetrigger so as In order to seat the head-ot the catch K onthe lip M, andprevent lateral motions thereof,

triggeris drawn baek,-the 1 i M is, lowered, and the catch K owing toitsspringy na-' tare; lowers and causes. its-head tdwithdraw unlocked.Thecha'mber rotates'as' usual, and

spring-pressed bolt or catch P, whoseheadis adaptedto enter a portion ofeither recess L in the chamber when the trigger is pulled, as

6g tend around the same at a right angle to the the chamber rotates, thehead of the former enters the approaching recess Q, and is thus in itsnormal position, the catch K is elevated -low ered,*as-most plainl-ys'hown in Fig.2, the catch-P is removed from said. recess, and-isthereby renderedinoperative; 'W-hen how- .recessL, which communicateswith the said chainberis locked by said catch P, this occurring j listinadvance otthe firing-or discharge ofthe pistol, and oon'tinuing untilthefiring is accomplished. See Fig. 3. The trigger now-returns to itsfirst position, whereby the catch P'is iowered,

ind the chamber is unlocked, but as the lip M rises, due to thereturning motion of the trigger, the head K is forced into the adjacentrecess L, thus again locking the chamber and preventing rotation of thesame, while being carried or handled until the trigger is drawnback,.when the operations hereinbefore described are repeated. It willbe ob-' served that the trigger is provided with a A spring S whichbears against the same and the frame, for raising the forward end of thetrigger and restoring it to its normal position after firing. g It willbe seen that during the operation of extracting the empty cartridgeshell, the chamber A is controlled by the catch D, and thus retained inposition without being disturbed by the action of the extractor.

Having thus described my invention,

what

I claim as new,and desire to secure by Letters :0

- Patent, is-

1. A fire arm having a rotary chamber with an annular recess in the rearend thereof, and a movable catch having one end freely entering saidrecess and adapted to be withdrawn '25 therefrom, substantially asdescribed.

2. A fire arm having a rotary chamber with an annular recess in the rearend thereof, a strap with a chamber therein, and a spring actuated catchin said chamber, said catch occupying an opening in said strap, andtheother limb freely engaging the end of the rotary chamber in said annularrecess, substantially as described.
